tlmn our own. In fact, the trees of Oregon flourish well in 

 the climate of England where njany of them have been in- 

 troduced, whereas, with us, excepting a very few species, 

 they would not survive a single season. 



Among the European trees of frequent occurrence in 

 cultivation here are the Norway Spruce, Linden, Sycamore, 

 Maple, English Oak. Scotch and Austrian Pines, European 

 Ash, each of which has its respective superior in the 

 American White or Blue Spruces, American Linden, Rock 

 Maple, White and Overcup Oaks, White and Red Pines, 

 and White Ash. 



Northern China and Northern Japan having climates 

 similiar to our own, for similar reasons furnish many trees 

 suited for our plantations, some of which have been success- 

 fully tried. The region of the Caucasus has furnished two 

 excellent trees likely to continue of value, the Picea orien- 

 talis and Abies Normaniana, while others have been intro- 

 duced from Siberia, Turkestan and Thibet. Among such 

 trees we have the Horse Chestnut which has proved itself 

 exceedingly desirable for certain situations as an ornamen- 

 tal tree possessing a stateliness unsurpassed by almost any 

 other tree, and furnishing, too, a magnificent show of flow- 

 ers in the latter part of the month of May. 



Among the trees from the Pacific slope are some, how- 

 ever, which have such an extended range that selecting 

 specimens or seeds from the extreme limits of their dis- 

 persion we are enabled to introduce them successfully here. 

 Two such trees are the Douglas Fir and Picea Pungens or 

 the Blue Rocky Mountain Spruce. These trees, although 

 not hardy when taken from California or when imported 

 from Europe, have proved themselves perfectly hardy when 

 introduced from Colorado. Specimens of both these beau- 

 tiful trees may now be seen in the neighborhood of Boston, 

 20 feet high and of beautiful form and growth.
